Siemens 6ES7332-5RD00-0AB0 SIMATIC S7-300 SM 332 4 AO 0/4-20mA Ex(i) Analog Output Module

The Siemens 6ES7332-5RD00-0AB0 is a SIMATIC S7-300 SM 332 isolated analog output module with 4 channels for 0/4 to 20 mA signals, rated for use with equipment in hazardous areas through Ex(i) intrinsic safety. It connects through a 20-pin front connector, provides overrange and wire-break diagnostics, and is PTB-tested (Ex-96.D.2026X) for ATEX [EEx ib] IIC and FM Class I Division 2 applications.

Technical Specifications

Selection Notes

The 15-bit resolution and +/-0.2% basic error limit at 25 C support accurate 4-20 mA loop measurement where analog readback quality matters downstream. Because the module carries [EEx ib] IIC Ex(i) approval (Uo 14 V, Io 70 mA, Po 440 mW), it can drive hazardous-area actuators directly from a standard S7-300 rack without external isolation barriers. The two-wire connection option on the current outputs cuts field wiring versus a four-wire loop, and the wire-break and overrange diagnostics flag faulty loops through the SF and F LEDs without extra wiring effort.
